ASX-listed Cooper Energy Limited said that the Bunian-4 appraisal/development well in the Tangai-Sukananti KSO, South Sumatra, has reached a total depth of 1,744 meters.
Wireline logging of the wellbore and installation of production casing is complete and preparations are being made to flow test the well.
?Preliminary results indicate that Bunian-4 has intersected 5.2 meters of net sand in the TRM3 Sandstone section 17 meters high to prognosis. The top of the primary target TRM3 Sand was intersected 470 meters east-southeast and 6 meters below the producing TRM3 Sand at Bunian-3,? the company said in a statement Monday.
?In addition to the successful appraisal of the TRM3 Sand a new zone designated the GRM Sandstone is identified as potentially hydrocarbon bearing. The net sand thickness intersected at the GRM Sandstone is 3.5 meters,? it added.
Cooper said potential in the secondary objective TRM1 and TRM2 Sands will be evaluated when the interpretation of wireline logs is complete.
The company explained that production casing has been run and a multi-zone production completion will be installed to allow each of the major hydrocarbon zones identified to be flow tested and produced independently shortly after the release of the drilling rig.
Cooper Energy Managing Director, David Maxwell said: ?The preliminary results from Bunian-4 are very encouraging, particularly the TRM3 Sand and the possibility of a new pool discovery in the GRM Sandstone?.
Joint venture participants in the Tangai-Sukananti KSO are Cooper Energy Sukananti Ltd (operator 55%) and Mega Adhyaksa Pratama Sukananti Ltd (45%).
